DUPLEX PARALLEL SHEARS.

SPECIFICATION forming' part of Letters Patent N 0. 596,213, dated December 28, 1897. Application led July 24, 1897. Serial No. 645,756. (No model.)

To aZZ whom it may concern,.-

Be it known that I, MAX LOEWENTHAL, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Duplex Parallel Shears, of which the following is a specification.

The object of my invention is to produce a device whereby the severance of columns of printed matter from paper or clippings can be made with precision and expedition, which invention may also be employed in other relations.

y My invention has special application to the cutting of clippings from newspapers, wherein it is desirable to cut an article from the paper at any one of the columns thereof.

At the present time, so far as I am informed, it is the custom to employ shears or scissors wherein but two oppositely-acting blades are employed,'the blades severing but one side of the column in their progress through the paper, and with this single-shear device in order to sever a column located within the limits of the outer columns or edges of the paper it has been necessary to go over each side of the column in order to sever it from the paper. l/Vith my duplex shears both of the sides of the column are severed simultaneously, requiring the ground to be gone over but once t0 completely sever the column from the paper. My improvements in this regard also embody means for accommodating the sets of shears to varying widths of columns.

My invention therefore consists in the combination of a plurality of sets of parallel shearing or cutting blades so connected that they can be operated simultaneously by a single handle to produce a shearing or cutting action at two or more points at the same time.

My invention further consists in the combination, with a plurality of sets of cuttingblades, of means for adjusting the distance between the cutting-blades and setting said blades in their position of adjustment.

My invention further resides in the construction and combination of parts hereinafter described, and more fully pointed out in the claims.

In the drawings forming part of this specilication, Figure 1 is a side elevation of a device embodying my invention; Fig. 2, a plan view; Fig. 3, a side elevation of one of the sets of shears, partly in section, on the line 3 3, Fig. 2, looking in the direction of the arrow; and Fig. 4 is an enlarged sectional ele- Vation through the blade connections on the line 4 4, Fig. 2, looking in the direction of the arrow.

Similar numerals and letters of reference indicate corresponding parts throughout the several views. 4 The embodiment of my invention illustrated in the accompanying drawings comprises two sets of shearing or cutting blades 1 2 3 4, each set of blades being pivoted together by separate and unconnected pivoting and tension pins or screws 5 6 of any desired construction. The blades 1 2 are extended rearwardly, as at 7 8, to form the usual handles 9 10, while the blades 3 4 are extended rearwardly from their fulcrum to form extensions 11 12.

As will be noted, the primary shears or set a, comprising the blades 1 2, is of the ordinary or usual construction, whereas the secondary or complemental shears or set b is of like construction, except that the extensions v11 12 from the pivot 6 are not formed into operating-blades, the ends of the extensions 11 12 being curved, as at 13, especially at their under side, to avoid presenting a sharp surface to the paper.

The duplex cutting instrumentalities comprising the sections d b are united for simultaneous operation in the following manner: To the outer blade 1, at the rear of its pivot 5, is rigidly secured an apertured bar 14,which may be hollow for its entire length or a portion thereof may be made integrally with the blade 1 or separately formed and secured thereto in any desired manner, as by forming a hole in the extension 8, threading it, and forming a like thread on the end of the bar 14 and securing the parts together.

Other means of connection may be employed. The extension 7 of the blade 2 is provided with a transverse and circular slot 15 to allow the blades to be vibrated to or from each other in the operation of shearing without interference with the bar 14. The extension 7 is likewise provided with an outwardly-extending bar 16, which may be an exact counterpart of the bar 14, with the exception of the parts hereinafter described. A clamping device 17, comprising the split lips or projections 1S 19, (the split c being continued along the side of the bar 14 for the desired distan-ce,) is formed on the end of the bar 14 and extends outwardly at right angles therefrom, the lower lip 19 of the clamp being provided with a rounded lug 20, as shown in Fig. 4, to allow it to ride easily over the paper, both of the lips being apertured and provided with screw-threads to receive the threaded stem 21 of the set-screw 22, the end of the stem 21 being prevented from striking the paper by the lug 20. Extending outwardly from the extensions 11 12 are two bars 23 24, the bar 23 being rigidly secured to the blade 3 in line with the aperture in the bar 14 and closely adjacent the pivot 6 and the bar 24 rigidly secured to the blade 4 in line with the aperture in' the bar 16 and to the rear of the bar 23, the extension 11 of the blade 3 being provided with a circular slot 25, Fig. 2, to allow the bar 24 to be vibrated without interfering with the movements of the blades 3 4. The bars 23 24 enter the apertures (which may be of any desired shape in cross-section) in the bars 14 16 and tie the respective blades, to which said bars are connected, together, so that the movement of the blades of the primary shears a will be communicated to that of the secondary shears b,caus ing all the blades to work in unison. The set-screw 22 iixedly secures both of the pairs of blades together.

As is apparent, the bars 23 can be moved in the direction of the length of the bars 14 16, telescoping the former into the latter to increase or diminish the distance between the blade-sections a b, the set-screw fixing them in their position of adjustment.

The points of each of the sets of blades are drawn out tine, as indicated at 26, Fig. 2, in order that the blades may be entered into the paper between its edges without tearing it.

The separation of the blades of the main' or primary shears a in the manner indicated in Fig. 3 separates the corresponding or com plemental blades of the secondary-shears section Y) by means of the connections hereinbefore described, and in like manner the corresponding blades of the shears are moved together when the blades of the main section a are so operated, causing the action of all of the blades t-o be synchronous.

l do not limit myself to the precise construction of parts hereinbcfore shown and described, as it is apparent that they can be modified in many ways without departing from the spirit of my invention.

Having described my invention, I claim- 1. The combination in an article of the class described, of the primary shears comprising the blades pivoted between their ends, secondary shears comprising a set oi pivoted blades disposed parallel to the primary set, an inflexible connection extending between the outer blade of the primary shears and the inner blade of the secondary shears, and a further inflexible connection extending between the inner blade of the primary shears and the outer blade of the secondary shears, substantially as described.

2. The combination in an article of the class described, of the primary -shears section ct comprising the blades 1, 2, having extensions 7, S and handles 9, 10, said blades being pivotally secured together intermediate their ends, a further set of blades 3, 4, disposed parallel to the blades 1, 2, and having extensions 11, 12, said blades being pivoted together intermediate of their ends, a bar extending between the blades 1, 3, and connecting them together, and a further bar extending between the blades 2, 4 and connecting them together, both bars being located at the rear of the fulcrum of each set of blades, substantially as described.

3. The combination with the two separate sets of blades, each set having a separate pivot and disposed parallel to each other, separate lateral extensions from each of the sets of blades, and means for adjustably securing said extensions together, the extensions being located at the rear of said pivots, substantially as described.

4. The combination with the blades 1, 2 pivoted together as at 5 and provided with operating-handles, the longitudinally-apertured bar 14 extending from the blade 1 at the rear of the pivot, a bar 16 extending outwardly from the blade 2 adjacent the bar 14 and to the rear of said pivot, the blades 3, 4 pivoted as at 6 and having extensions 11, 12, a bar 23 extending outwardly from the extension 11 to the rear of said pivot and movably engaging the bar 14, and another bar 24 extending outwardly from the extension 12 and movably engaging the bar 16, and means for securing either of the opposing bars together, substantially as described.
